Classification

Bladder injuries can be either extraperitoneal (the peritoneum is intact and urine extravasates into the retropubic space but not into the peritoneal cavity), intraperitoneal (the peritoneum over the bladder is injured and urine extravasates into the peri toneal cavity) or mixed ( Table 83.18 ). Intraperitoneal ruptures are associated with a risk of urinary peritonitis and ileus, and so are more significant than extraperitoneal ruptures.
